Common market health measures such as GDP and GNP have been used as a measure of successful policy. On average richer nations tend to be happier than poorer nations, but this effect seems to diminish with wealth.   This has been explained by the fact that the dependency is not linear but logarithmic, ., the same percentual increase in the GNP produces the same increase in happiness for wealthy countries as for poor countries.     Increasingly, academic economists and international economic organisations are arguing for and developing multi-dimensional dashboards which combine subjective and objective indicators to provide a more direct and explicit assessment of human wellbeing. Work by Paul Anand and colleagues helps to highlight the fact that there many different contributors to adult wellbeing, that happiness judgement reflect, in part, the presence of salient constraints, and that fairness, autonomy, community and engagement are key aspects of happiness and wellbeing throughout the life course.
